The first memory Stick

This makes me thankful for technology:
Abdul Kassam Ismael, Grand Vizier of Persia in the tenth century, carried his library with him wherever he went. Four hundred camels carried the 117,000 volumes.
Can you imagine hauling around all of those books?
Do you carry a memory stick, what kind of info is on there?
I carry one with my business info. That way I don't have to haul my lap top around. When I go to a clients place of business, I can just stick in the stick!
